When its all assembled the drive spring will pull the whole thing over. Unless you are keen to undertake extra work I would suggest you forget you noticed it. :rofl:

Quite agree with Clive.
Some end float is necessary to confirm that there is no preload on the crank assembly when the c/case halves are bolted together. Any preload on the crank assembly due to it being constrained axially between the timing side bush and the main bearings would result in the thrust face of the timing side bush wearing away and cause accelerated wear of the ball main bearings.
